Mechanical and chemical weathering  By, Autumn Baxter 

Ice wedging Freeze- thaw crack widens or gets bigger This is mechanical Mechanical means- is broken down external conditions

Wind Abrasion Sand Blasting This rock is mechanical Mechanical means- is Broken down external conditions

Water Abrasion Smooth and round Water Abrasion is mechanical Mechanical means- Broken down external conditions

Gravity Abrasion Cooling and breaking down, repeated impact Gravity Abrasion is mechanical Mechanical means- Broken down external conditions

Plants  Roots breaking or cracking it. Plants are mechanical Mechanical means- Broken down external conditions

Animal bURROWING Animal Burrowing digging breaking it up Animal Burrowing is mechanical Mechanical means- Broken down external conditions

Acid Precipitation Burning Chemically with water. Acid Precipitation`s is a Chemical Weathering Chemical weathering means – Break down rock by chemical changes

Acid in Groundwater In groundwater chemically break down Acid In groundwater is a Chemical weathering Chemical weathering means – Break down rock by chemical changes

Acids in living things Chemical weathering inches produce. Acids in living things is chemical weathering Chemical weathering means – Breaking down rock by chemical changes

Rusting or oxidation Iron or soil rusting. Rusting or oxidation is Chemical Weathering Chemical weathering means – Breaking down rock by chemical changes
